Following is the molecular structure of Phencylidine (77-10-1):

Phencylidine (77-10-1) was first synthesized in 1926, and later tested after World War II as a surgical anesthetic. Because of its adverse side effects, such as hallucinations, mania, delirium, and disorientation, it was shelved until the 1950s. In 1953, it was patented by Parke-Davis and named Sernyl (referring to serenity), but was withdrawn from the market two years later because of side-effects. It was renamed Sernylan in 1967, and marketed as a veterinary anesthetic, but again discontinued. Its side effects and long half-life in the human body made it unsuitable for medical applications.

Poison by intraperitoneal route. Experimental reproductive effects. Caution: This is a controlled substance (depressant) listed in the U.S. Code of Federal Regulations, Title 21 Part 1308.12 (1985). The ethylamine, pyrrolidine and thiophene analogs are listed as hallucinogens, Title 21 Part 1308.11. When heated to decomposition it emits toxic fumes of NO_x.

Phencyclidine (77-10-1)(a complex clip of the chemical name phenylcyclohexylpiperidine, commonly initialised as PCP), also known as angel dust and other street names, is a recreational, dissociative drug formerly used as an anaesthetic agent, exhibiting hallucinogenic and neurotoxic effects. Developed in 1926, it was first patented in 1952 by the Parke-Davis pharmaceutical company and marketed under the brand name Sernyl. In chemical structure, PCP is an arylcyclohexylamine derivative, and, in pharmacology, it is a member of the family of dissociative anesthetics. PCP works primarily as an NMDA receptor antagonist, which blocks the activity of the NMDA receptor. Other NMDA receptor antagonists include ketamine, tiletamine, and dextromethorphan. Although the primary psychoactive effects of the drug lasts for a few hours, the total elimination rate from the body typically extends 8 days or longer.
